Any civility rule that is enforced with greater priority than (or in the absence of) a “no bigotry” rule serves only to protect bigots from decent people.

There’s a saying I think about a lot that goes “The problem with rules is that good people don’t need 'em, and bad people will find a way around 'em”.

The best thing about human volunteer mods vs automated tools or paid “trust and safety” teams, IMO, is that volunteer humans can better identify when someone is participating in the spirit of a community, because the mods themselves are usually members of the community too.
